42、 objective because the reporters voice is rarely 100 percent neutral.

47、 good evidence that, there is no doubt that, it seems /appears that. Besides that, modals also help pinpoint the reporters voice: may, might, can, could, should, and ought to.,新核心大學英語B版聽說教程Uni2,Word Bank,Unit 2 Part II Section I Task 1,新核心大學英語B版聽說教程Uni2,Task 1 Listen to the following news for key wo
